I know someone has already asked, but how do you get out of the distorted sewer puzzle with the lights and well and large rusted wheel? I swear I have run around the entire area 5 times over, and have pulled every lever I found, but there are still plenty of locked doors and I can't get anywhere. Is that a bug with some doors not opening with their respective levers, or am I missing something?
Think back to the order the game introduces those colored lights to you when you first enter that area. You don’t need any new clues in the sewer room itself—just recreate the same sequence there and only then touch the big wheel. If you follow the path your character naturally takes the first time, the solution kind of reveals itself.
